EPCOS develops, manufactures and markets electronic components modules and systems, focusing on fast-growing leading-edge technology markets: in IT and telecommunications, but also in automotive, industrial and consumer electronics. A uniquely broad product portfolio and truly global presence have made EPCOS a global market leader in products that account for 60 percent of our sales. A further 30 percent is generated by products in which we are the number one in Europe.

In SAW components, ceramic components, capacitors and inductors alike, EPCOS consistently stands for superlative electronic performance. About 18,300 employees at over 20 design and production locations and a tightly meshed sales network give us a genuine global footprint. We serve our customers with about 700 sales professionals, around half of whom are engineers and technical experts.

Electronic components are found in nearly all electrical and electronic devices. A single car can contain as many as 10,000 such components, for example. In mobile phones and lighting ballasts, notebooks and electric locomotives, electronic components are instrumental in processing electrical signals, protecting electronic circuits and ensuring a regular, reliable power supply.

Capacitors are used throughout electrical engineering and electronics. They store electric charges and filter or regulate current and voltage in electronic circuitry. Our product portfolio includes aluminum electrolytic capacitors, film capacitors and power capacitors, and solutions for power factor correction.

Inductors fulfill two basic electrical functions at the same time: they filter current and store electromagnetic energy. Inductors are, for example, used in switch-mode power supplies for applications in IT, telecommunications, consumer electronics, industrial electronics and automotive electronics. Our portfolio also includes ferrites, which are the heart of inductors and concentrate electromagnetic fields to transmit electrical signals and power. Moreover, EPCOS also manufactures  components that ensure electromagnetic compatibility (EMC) for the interference free operation of electrical equipment and devices of all kind.

Ceramic components are indispensable in automotive electronics and household appliances in particular, but also in telecommunications and entertainment electronics. They filter electrical signals, measure physical quantities (such as temperature) and protect electronic circuitry against overvoltage and overcurrent. Our product portfolio covers surge arresters and switching spark gaps, sensors and sensor systems, thermistors, varistors, and a wide range of multilayer ceramic components, including piezo actuators and capacitors.

Surface acoustic wave components (SAW components), integrated radio frequency modules and microwave ceramic filters are key components of modern information and communications. They select frequencies and have a crucial impact on picture and sound quality in audio and TV equipment as well as in mobile phones, for example. Our California-based subsidiary Crystal Technology, Inc. is the global leading manufacturer of lithium niobate crystals and wafers, which are the raw materials for many SAW components.

EPCOS was floated simultaneously on the Frankfurt and New York Stock Exchanges on October 15, 1999. The listed company emerged from Siemens Matsushita Components, a joint venture founded in 1989 by Siemens and Matsushita. Because of the low trading volume, EPCOS has decided to delist and to deregister from the New York Stock Exchange in November 2007. Since March 2003, EPCOS has been one of the largest companies in the TecDAX index of German technology stocks.
